The final piece of the Ares I-X rocket arrived at KSC on Thursday. The first stage segments trekked their way across the country (2,917 miles!) from ATK in Utah to KSC in Florida. They came by rail car and pulled in Thursday afternoon.
This is a big deal because the motor segments are the last piece of major hardware to ship. Now with the major hardware elements at the launch site, we can really get into stacking and watch the rocket take shape.
These motor segments that we’re using for the first stage are from the space shuttle’s inventory — that is they were originally built for the shuttle. Ares I-X made some modifications and added some new components to make them work for the flight test.
The first stage booster packs a punch too. It can generate 3.3 million pounds of thrust, and we’ll need every bit of that to launch the rocket. The first stage will give Ares I-X it’s lift-off capability and power it through the first 120 seconds of flight. When the motor is spent, it will separate and parachute back to Earth and be recovered and towed back to land to be reused.
